Features & Capabilities

This browser extension helps you generate detailed, accessible alt text for images and videos you add to posts on Bluesky, using Google Gemini AI.

Once installed, the extension is active on bsky.app. When you upload an image or video and open the alt text input field (usually by clicking "ALT" or a similar button on the media preview), you will see a ✨ icon appear next to the text area. Click this icon to generate alt text based on the media. Review: Always review the generated alt text before posting! AI can make mistakes. The generated text will appear in the input field, and a toast notification will confirm success or report errors.

User Reviews

i mean it does work as an extension, but it doesn't generate alt text due to some server errors it seems?

This add-on is really helpful for when I'm too lazy to write out a proper caption for screen-readers. It is also surprisingly quick, while maintaining accuracy. :)

Is Bluesky Alt Text Generator Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Bluesky Alt Text Generator requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Bluesky Alt Text Generator is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
